Hi there!
For the final challenge, I decided to try out building a crane. And as I wanted something that it could move around, I thought why not some gleamy Suzannes I had some trouble rendering the background image in the second image (which I had added to the world in the camera settings, I can see it when looking through the camera but not when rendering). Also the rendering with cycles looked a bit strange so I kept the default rendering engine.
Feedback and ideas are welcome!!
Cheers
Nicolas
